Description

Located on one of the upper East Side's most desirable tree lined side streets, this sophisticated one floor walk-up townhouse apartment has large rooms and an enormous amount of old world charm. One enters the apartment through a gracious foyer/dining room, decorated with a fantasy mural painted with exotic birds under a colonnade with faux marble pilasters overlooking island pavilions set in an azure blue sea and sky, leading into the inviting, south-facing, richly-decorated living room with fireplace and windows facing the buildings opposite. The bedroom, currently with a Murphy bed, has ample closets and an en suite windowed bathroom. There is an additional powder room off the foyer. Fully equipped kitchen. Thru-wall air conditioning. This spacious property, lavishly decorated years ago to a very high standard, needs upgrading but has enormous potential. There is private storage and a laundry in the basement. The building has ten units and a part-time super.

About Upper East Side

View All Upper East Side Listings

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
